A 3000-lb car is traveling on a paved road with Cd (coefficient of drag) = 0.35, Af (frontal area of the vehicle) = 21ft^2, and p(air density)=0.002378 slugs/ft^3. Its engine is running at 3000rpm and is producing 250ft-lb of torque. The car's gear reduction ratio is 3.5 to 1, driveline efficiency is 90%, driveline slippage is 3.5%, and the road-wheel radius is 15 inches. What will the car's maximum acceleration rate be under these conditions on a level road? (Assume that the avilable tractive effort is the engine-generated tractive effort.)
